Safety & protection
Fire FightingExcerpt from ERG Guide 130 [Flammable Liquids (Water-Immiscible / Noxious)]:
Accidental Release Measures
· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.
· ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area.
First Aid
Call a physician.
General First Aid:
Exposure Control and Personal Protection· Wear positive pressure self-contained breathing apparatus (SCBA).
Nonfire Spill ResponseExcerpt from ERG Guide 130 [Flammable Liquids (Water-Immiscible / Noxious)]:
Isolation and Evacuation
Excerpt from ERG Guide 130 [Flammable Liquids (Water-Immiscible / Noxious)]:
Immediate precautionary measure
Personal Protective Equipment (PPE)Approved respirator, safety goggles, chemical-resistant gloves, other protective clothing. (USCG, 1999)
Emergency Response Planning GuidelinesCAUTION: The majority of these products have a very low flash point. Use of water spray when fighting fire may be inefficient.
